The future of the world's forests is at the forefront of environmental debate. Rising concerns over the effects of deforestation and climate change are highlighting the need both to conserve and manage existing forests and woodland through sustainable forestry practices. The Forests Handbook, written by an international team of both scientists and practitioners, presents an integrated approach to forests and forestry, applying our present understanding of forest science to management practices, as a basis for achieving sustainability. Volume One presents an overview of the world's forests; their locations and what they are like, the science of how they operate as complex ecosystems and how they interact with their environment. Volume Two applies this science to reality; it focuses on forestry interventions and their impact, the principles governing how to protect forests and on how we can better harness the enormous benefits forests offer. Case studies are drawn from several different countries and are used to illustrate the key points. Development specialists, forest managers and those involved with land and land-use will find this handbook a valuable and comprehensive overview of forest science and forestry practice. Researchers and students of forestry, biology, ecology and geography will find it equally accessible and useful.
Most of the attention with respect to the increase in atmospheric greenhouse gas concentrations centers around three issues: human-generated sources of carbon, mostly from burning fossil fuels; tropical deforestation, which accelerates the production of atmospheric carbon while causting havoc with biodiversity and the economic development of tropical countries; and the temperature increase that may accompany increased atmospheric greenhouse gas concentrations. This is the first book to focus extensively on the reverse to emissions of carbon dioxide (CO2), i.e. the sequestering of atmospheric carbon by aquatic and terrestrial ecosystems. Natural ecosystems are currently sequestering carbon and it is economically feasible to manage existing and additional terrestrial (forest, soil, saline land) and aquatic (coastal, wetland and ocean) ecosystems to substantially increase the level of carbon storage. The prospect of managing natural systems to absorb additional carbon should begin to change the mindset under which scientists, policy makers and society deal with the issue of further greenhouse gas increases.
In the past decade, there has been much debate over the environmental impact of forestry. People are justifiably concerned about what is happening to the local and global forest environments, but they are also confused by the polarized rhetoric that has characterized both sides of the debate. In Balancing Act, Hamish Kimmins calls for a balanced, more objective approach to forestry issues in order to bridge the gap between the most extreme opponents in the debate. He suggests that we need to begin with a common understanding of what forestry is about and how forest ecosystems work. He outlines the scientific and ecological aspects of the major environmental issues facing British Columbia and the world today, arguing that we need to disentangle the scientific from the value-based social aspects of these questions. He also contends that much of the current debate about forests and their management ignores the time dimension of ecosystems, and he calls for a more dynamic view of current environmental issues in forestry -- one that accounts for change. The first few chapters provide an outline of the basic principles of forestry and ecology, and subsequent chapters discuss the major environmental issues facing forestry in the 1990s. These include clearcutting, slashburning, management chemicals, old growth, biological diversity, 'new forestry, ' climate change, acid rain, the comparison between temperate and tropical forestry, and long-term decisions in forestry. Balancing Act is essential reading for those who are searching for an objective, accurate, and readable evaluation of the issues at the heart of the forestry/environment debate. By emphasizing that forests are not static but change over time, Kimmins adds an important, often ignored, dimension to the discussion. Only by understanding all the intricacies of the ecosystems can we learn to manage our forests in a sustainable fashion.
Forest damage, forest decline, forest dieback - not related to biotic agents - is occurring in the Atlantic and Pacific regions. In Europe and Eastern North America this serious problem is considered to be, at least to some part, related to industrial air pollutants and their atmospheric conversion products, such as acid rain or ozone. Forest declines in the Pacific region have been attributed largely to natural causes involving forest dynamics, since air pollution and other negative anthropogenic influences are practically absent. Presented here are typical decline phenomena in the Pacific and Atlantic region, potential causes, effects and mitigation strategies, and the question whether there are any similarities on a functional or structural basis is addressed.
The book contains articles covering a wide range of subjects of environmental science. The terrestrial section has articles on air pollution, solid waste ground water regime, western ghats, eastern ghats, mining, medicinal, plants, ethnobotany, role of pesticides, agriculture, microbial sensors, wetlands and ornithological studies. The marine environmental aspect such as mangroves, application of remote sensing, harmful algal blooms, bio-remediation, sustainable management of molluscan resources, benthic fauna, deep seabed mining and bio-fouling have been dealt in the marine environment section.
